- Seaports face significant environmental challenges in their role as hubs for logistics activities, particularly since ships are significant contributors to energy consumption, global warming and air and marine pollution. The environmental pressures facing ports has led to the emergence of the green port concept. Port Klang is the largest port in Malaysia, characterised not only by significant container throughput, but also by significant congestion issues, emissions and pollution. These characteristics led to the selection of Port Klang, the nation's major seaport, as a case study for this analysis of the variables most relevant in the effective implementation of the green port concept and subsequent research into how this green seaport concept influences a seaport's future competitiveness. To achieve these aims, the Analytic Hierarchy Process (AHP) has been employed. The findings of the analysis suggest that environmental quality, the use of energy and resources, waste handling and habitat quality and greenery are the critical influential factors required for establishing green port hub status and that then port competitiveness is most significantly affected by green operations, sustainable equipment, resources management and cost efficiency at seaports.

- Ensuring maritime safety has ascended as a preeminent concern within the global maritime sector. Understanding how factors affect maritime accidents’ consequences in different water areas would be of great benefit to preventing the occurrence or reducing the consequences. This study thus employed a multi-scale geographically weighted regression (MGWR) model on the accident dataset from Fujian waters in the East China Sea, to quantify the influences of different factors as well as the spatial heterogeneity in the effects of key factors on maritime accident consequence. The performances of MGWR are compared with multiple linear regression (MLR) and GWR. As expected, MGWR outperforms the other two models in terms of its ability to clearly capture the unobserved spatial heterogeneity in the effects of factors. Results reveal notably distinct influences of some factors on maritime accident consequences in different locations. An intuitive indication by MGWR is that approximately 50% of the accidents present positive coefficients of good visibility while other locations are negative, which are failed to recognize by MLR. The outcomes provide insights for making appropriate safety countermeasures and policies customized for different water areas.

Tidskriftsartikel (refereegranskat)abstract
- Due to the constant risk of piracy and terrorist attacks which cause disturbances within international shipping of goods, barriers to the adoption of maritime security guidelines (MSGs) at European ports have become prevalent. In this paper, a conceptual framework was created to explore the perceived barriers that prevent compliance with MSGs. To verify the conceptual framework, empirical data were collected using a mixed-methods approach, which was comprised of interviews with national experts and a survey of 47% of Swedish ports involved in the shipping of goods. According to the presented framework, the perceived barriers of Swedish ports to compliance with MSGs were linked to collaborations within the Swedish Maritime Security stakeholder network, available resources and educational knowledge about security culture. In addition, the perceived barriers of smaller ports were linked to the adaptation to MSGs at different levels and the absence of specific tools of maritime security management. Due to an increased interest in international shipping of goods, this paper is currently one of few that addresses the barriers to compliance with MSGs. Moreover, the paper presents a general conceptual framework, novel managerial implications and recommendations for future research.

Tidskriftsartikel (refereegranskat)abstract
- The objective of this paper is to simultaneously analyse the complex relationships between bilateral maritime connectivity, bilateral trade and domestic production as measured by gross domestic product (GDP) per capita. This is achieved by applying non-recursive models and Path Analysis (PA). The top ten best maritime connected countries and their 155 trading partners are selected for the analysis. The components of maritime connectivity, maritime distance, and gravity variables are selected as instrumental variables to analyse the reciprocal relationship between export/import of ten countries and the GDP per capita of their 155 trading partners. The results confirm the reciprocal relationship between export values (that are the import values of trading partners) and GDP per capita, whereas a reciprocal relationship between import values (that are the export values of trading partners) and GDP per capita does not exist. The results also confirm the complexity of the relationships between maritime connectivity, trade and economic growth and that, compared to components of maritime connectivity, none of the gravity variables have a positive impact on bilateral trade. The results suggest that economic policy and trade policy at the global, regional, and national level should recognize the need for, and foster, better maritime connectivity.

Tidskriftsartikel (refereegranskat)abstract
- China is ranked as the number one maritime connected country in the world. This study attempts to analyse the characteristics of its 155 maritime trading partners. Five components of maritime connectivity have been used for the analysis. A hierarchical clustering technique is applied to group the trading partners into distinct meaningful clusters. As China's main maritime competitors within the East Asian region, the analysis is also applied to Singapore and Hong Kong. The clustering technique produces three distinct clusters for China and Singapore and two for Hong Kong. The results reveal the importance of direct maritime connectivity, with China having the highest number of trading partners with zero transhipment (including its top 15 trading partners), compared to Singapore and Hong Kong. The analysis is further extended by applying ordered logistic regression. The results show that the logistic performance index (LPI) and exports/imports have a positive and significant influence on clusters. Conclusions are drawn as to the potential for implementing strategies and policy interventions on the basis of the emergent clusters, particularly the need for Hong Kong to improve all five components of maritime connectivity in order to compete with China and Singapore.

- The International Maritime Organization (IMO) has implemented a series of increasingly stricter regulations to reduce sulphur emissions from international shipping. As of January 2020, the global sulphur cap requires the use of fuel containing a maximum of 0.5% sulphur content, or the use of technology achieving a similar reduction in sulphur emissions. Deciding between fuel switching or investing in abatement technologies has been a recurring topic for research in the last decade, with a focus on shipping activities within Emission Control Areas (ECAs). The quest for the desulphurization of shipping results in higher operating costs as well as CO2 emissions. We estimate the economic and environmental impacts of compliance with sulphur limits for a variety of representative ship types. This paper quantitatively assesses case studies across the most important shipping sectors highlighting their different challenges. The results confirm that scrubber investments are more profitable at times of higher fuel prices, and for ships that spend relatively more time sailing. We show that the potential for speed differentiation inside and outside ECAs has been diminished. This framework can be a useful decision support system for selecting the best response amongst different compliance options to environmental regulations.
